ARTIFICIAL DENTURE.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed February 10, 1906. Serial No. 300,465.

To all whom it 777/017] concern.-

Be it known that we, PHILLIP B. Lnsn- MANN, a resident of Nashville, in the county of Vashington, and SAMUEL J .IJESEMANN, a resident of Altamont, in the county of Ethngham, State of Illinois, citizens of the United States, have made certain new and useful Improvements in Artificial Dentures, of which the following is a specification.

This invention is an improvement in artificial dentures, and has for an object to provide a novel means whereby to secure an artificial tooth to a mouth-plate, being especially intended to enable the ready substitution of a new for a broken tooth on a vulcanized plate without revulcanizing the plate; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a detail perspective view of the anchoring-staple. Fig. 2 is a detail perspective view illustrating a tooth with the staple applied thereto. Fig. 3 is a detail section on about line 3 3 of Fig. 5, showing a portion of a mouth-plate with the tooth anchored in place, according to our invention. Fig. a is a front elevation of the mouth-plate, some of the teeth being removed to show the cavities for the anchoringstaples; and Fig. 5 is a detail section on about line 5 5 of Fig. 3. Fig. 6 is a detail view showing the invention applied to a tooth having pins arranged in a vertical series instead of a transverse series, and Fig. 7 shows a tooth having a single pin with the anchoring-staple applied.

The mouth-plate A and artificial tooth B may in general respects be of ordinary construction, the tooth B being provided with headed pins C, such as are commonly employed for anchoring teeth to vulcanized p ates.

The anchoring device comprises, as shown in Figs. 1, 2, 3, and 5, a staple formed from a length of metal which maybe square in crosssection, as shown, or of any other suitable form, and such rod or bar is bent to form the side bars D, which are connected at their inner ends, and are provided adjacent to said inner ends with lateral loops I), which are bent in the use of the device around the headed ins C, and from these loops extends outward? practically in the same general direction as the side bars D, a bend or loop D which together with the side bars forms a secure anchorage in the cement in the mouthplate in the application of the invention. These lateral loops D and the longitudinal loop D it will be noticed, are integral with the side bars D, and the device, as shown in Fig. 1, with the loops D and D spread or open, is readyfor placing on the market as a means for attaching artificial teeth to a mouth-plate. The side bars D are provided with deflected portions (1, preferably formed by bending the extremities of said side bars, as shown in Figs. 1 and 2, for the purpose of increasing the anchoring hold of the said side bars in the cement when the device is applied for use.

It will be understood that the purpose of this invention is to make it possible to replace in a practical manner a broken tooth on a vulcanite (rubber plate) without revulcanizing the plate, thus saving much time and labor, and also avoiding the danger of warping or altering the plate, as well as avoiding increasing the brittleness of the plate by revulcanization.

In carrying out the invention, Where a tooth is broken from a plate A a cavity E is cut in the plate A leading from the tooth-seat F and made of sufiicient size and depth to receive the anchoring-staple and to permit the setting of the tooth in proper position. The staple having been bent into connection with the tooth, as shown in Fig. 2. ccment-such, for instance, as oxyphosphate cement-is mixed and placed. in the cavity in the vulcanized plate and also over the staple and back of the tooth, and the staple is pressed into the cement in the cavity, the tooth placed in proper position, and the excess of cement trimmed away, when the re pair will be completed with the parts firmly bound together by the cement.

It will be noticed that the invention comprises, broadly, an anchoring device looped into connection with the pin or pins of an artificial tooth and projecting thence to enter acavity in the mouth-plate.

It will be understood that while we prefer to make the staple in the form shown in Fig. 1 we reserve the right to alter the connecting device in minor details, such as different sizes, gage of metal, character of metal, va-

riations in shape and the corrugations or defiections, such as d, for increasing the anchoring hold of the device in the cement. It will also be understood that while we have shown our anchoring device in connection with a tooth having two pins it may be applied to a tooth having but one pin and can also be attached to a tooth having two pins arranged vertically instead of crosswise, and we do not desire to be limited in the broad features of our invention to the specific construction as shown and before described.

In Fig. 6 we show a tooth having the pins arranged vertically instead of crosswise, as shown in Fig. 2, the bars of the anchoringstaple being arranged at a somewhat di'fl'er ent angle from that shown in Fig. 2, while in Fig. 7 we show a large tooth or part of what is known as a gum-section having one pin with a staple attached, the staple shown in Fig. 7 being secured by cutting one of the double staples, such as shown in Figs. 1 and 2, in two parts, using a half staple for connection with the pin on the tooth.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. As a means for attaching artificial teeth to a mouth-plate, an anchoring-staple provided with side arms deflected at their eX- tremities whereby to increase their anchoring hold in a cement bed, the said side arms being connected at their inner ends and provided adjacent to said ends with loops for connection with tooth-pins and having between said loops an outwardly-projecting loop extending approximately in the direction of the side arms of the staple, substantially as and for the purposes set forth.

2. As a means for attaching teeth to a mouth-plate, an anchoring device consisting of a rod or bar looped at one end to clamp around a tooth-pin and having adjacent to its free extremity a deflected portion whereby to dincrease its anchoring effect in a cement be 3. A device for attaching artificial teeth to a mouth-plate consisting of a staple having side arms connected at their inner ends and provided adjacent said ends with loops for connection with tooth-pins.

4. As a means for attaching artificial teeth to a mouth-plate, an anchoring-staple bent between its ends forming loops for connection with toothpins andhaving the side bars provided with deflected portions for increasing their anchoring effect in a cement bed.

5. The combination of a mouth-plate having a cavity or recess, an artificial tooth having a headed pin, and an anchoring-rod bent at one end around the pin into clamping con tact therewith and projecting thence into the cavity in the mouth-plate, and cement securing the anchoring device in said cavity.
